Turkcell Iletisim Hizmetleri shares declined after the company released its Q1 2026 results after Borsa Istanbul trading hours on May 11. The stock was down 3.45% to trade at 117.7 as investors parsed a mix of solid top-line growth and signs of margin compression.
The telecom operator reported first-quarter revenue of TRY 68.4 billion, an increase of 8.9% year-over-year, supported in part by the nationwide launch of its 5G services. Despite the revenue gain, the company recorded a contraction in EBITDA margin of 2.3 percentage points to 41.4%.
Net income improved, rising 15% year-over-year to TRY 4.63 billion. Still, the reduction in profitability on an EBITDA margin basis appears to have been the primary catalyst for the immediate selling pressure, as investors weighed the trade-off between growth from new services and narrower margins.
Turkcell's 2026 guidance calls for real revenue growth in a 5% to 7% range, an EBITDA margin between 40% and 42%, and a capital expenditure intensity of roughly 25%. The company also expects data center and cloud revenue to grow 18% to 25% after a normalization period following capacity expansions in 2025.
The combination of relatively modest margin guidance and continued high capital spending linked to the 5G buildout may have tempered expectations for a swift recovery in profitability. Analysts remain broadly favorable on the name: the consensus 12-month price target is TRY 147.98, and 12 analysts recommend buying the stock while no sell ratings are reported. That positioning suggests the recent pullback is being treated by many as a short-term market reaction rather than a fundamental re-rating.
Macro conditions in Turkey present additional headwinds. Headline inflation rose to 31.5% in February, and the central bank previously increased its overnight reference rate by 300 basis points to nearly 40% to try to limit a deeper lira depreciation. At the same time, the BIST 100 index traded around the 15,066 level today after opening at 15,033, offering limited broad-market support to offset company-specific weakness in Turkcell.
The shares remain below their 52-week high of 129.6 but above the 52-week low of 86.78. Market moves following the earnings reveal a recalibration of near-term earnings expectations amid an investment-heavy 5G cycle and a challenging domestic macroeconomic environment, rather than an outright abandonment of Turkcell's longer-term growth prospects in digital services and 5G.
Bottom line: Turkcell reported revenue and net income growth in Q1 2026, but margin compression and a capital-intensive outlook tied to 5G deployment contributed to a share-price decline. Analyst consensus remains positive, indicating the market reaction may be largely tactical.
